Huge bruise on my stomach.. *Warning pic*

So I woke this morning and was getting ready to shower and when I looked in the mirror after taking off my hoodie I noticed this really huge bruise on my stomach. It freaked me out a bit because I haven't bumped into anything or been hit by anything to my knowledge... It doesn't hurt. Even when I poke it or rub over it, no pain whatsoever. I can't afford to see a doctor, and don't actually have insurance, but I was wondering if any of you ladies knew of something that might cause a bruise like this one? (pic will be down a bit in this post.)
It's probably about two inches wide, almost a perfect circle, and purple.. I have no idea how old it is.. but I would think it's a touch old because of how one part of it looks almost like an old bruise... Any input is appreciated.

Quoting MzDENISE:" It doesn't look like an old bruise to me, when the bruise is older, it will be more yellower and greener ... [snip!] ... and greener than it would be purple. That's so weird that you got a bruise out of no where. You don't sleep walk do you? "

I don't sleep walk.. once I'm in a comfortable position I'm there until I wake up... there's a spot on it near the top that's actually a bit yellow as if it's older than the rest is why I said that.. ><

You could call one of those ask-a-nurse hotlines, but its probably nothing and they will just say that you need to be seen to be sure. That is a pretty gnarly bruise so I think you should watch for others just in case, but if it doesn't keep happening I wouldn't worry.

That's what I'm thinking.. if I had more minutes on my phone I'd call one.. as far as I know I don't have any other bruises and this is the first time I've ever had one show up this bad.. usually they're smaller than a quarter and nowhere near as dark...

Once I woke up and alllll over my lower tummy and near my thighs were bruises I had probably like 20 in total. They hurt though. and I had no idea where they came from. I always bruise and I hate it. were you bitten by a spider or anything? My mom got bit by a spider and got a HUGE bruise like that then it started to get worse and she went to the doctor who said she was bitten by a brown recluse spider. It could be sooo many things! I'd go to your doctor though!

That scares me because they're actually common where I live....
I'm just gonna keep an eye on it for now, if it gets worse I'll go to a clinic or something...
